There are many reasons that an intranasal vaccine against the SARS-CoV-2 virus would be helpful in the fight against COVID-19 infections, University of Alabama at Birmingham immunologists Fran Lund, Ph.D., and Troy Randall, Ph.D., write in a viewpoint article in the journal Science.
The body's first encounter with the coronavirus happens in the nose and throat. New work in Cell suggests that responses in this early battleground help determine who will develop severe COVID-19 and who will have only mild or no illness. It used single-cell RNA sequencing of all the cell types recovered from nasal swabs of people with and without COVID-19.
Many species within Kenya's Tana River Basin will be unable to survive if global temperatures continue to rise as they are on track to do - according to new research from the University of East Anglia. A new study published in the journal PLOS ONE outlines how remaining within the goals of the Paris Agreement would save many species. The research also identifies places that could be restored to better protect biodiversity and contribute towards global ecosystem restoration targets.
A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers at Ruhr-Universität Bochum. They used an opsin - a protein that occurs in the brain and eyes - from zebrafish and introduced it into the brain of mice. Unlike other optogenetic tools, this opsin is not switched on but rather switched off by light. Experiments also showed that the tool could be suitable for investigating changes in the brain that are responsible for the development of epilepsy.
About six gigatons -- roughly 12 times the mass of all living humans -- of carbon appears to be emitted over land every year, according to data from the Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite (TanSat).
A phenomenon known from quantum systems could now make its way into biology: In a new study published in Physical Review X, researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) in Goettingen show that the notion of topological protection can also apply to biochemical networks. The model which the scientists developed makes the topological toolbox, typically used only to describe quantum systems, now also available to biology.
The EU funded project DAFNE has developed a methodology for avoiding conflicts of use in transboundary rivers. The model-?based procedure allows for participatory planning and cooperative management of water resources. The aim is now for the DAFNE methodology to be implemented in other regions of the world.
Scientists have identified five new plant species in the Bolivian Andes. The species are all part of the genus Jacquemontia, which are twining or trailing plants with pretty blue flowers.
After gaining world attention by 'unboiling' egg protein, Flinders University scientists have now used an Australian-made novel thin film microfluidic device to manipulate Beta-lactoglobulin (β-lactoglobulin), the major whey protein in cow's, sheep's and other mammals. In the latest application, published in Molecules, College of Science and Engineering experts have combined the capabilities of the VFD with a new form of biosensor called TPE-MI, which is an aggregation-induced emission luminogen (AIEgen).
Scientists have created plants whose cells and tissues 'blush' with beetroot pigments when they are colonised by fungi that help them take up nutrients from the soil. This is the first time this vital, 400 million year old process has been visualised in real time in full root systems of living plants. Understanding the dynamics of plant colonisation by fungi could help to make food production more sustainable in the future.
